Image and Backup logical Drives and Partitions

DriveImage XML is an easy to use and reliable program for imaging and backing up partitions and logical drives.

Image creation uses Microsoft's Volume Shadow Services (VSS), allowing you to create safe "hot images" 
even from drives currently in use. Images are stored in XML files, allowing you to process them with 3rd 
party tools. Never again be stuck with a useless backup! Restore images to drives without having to reboot.
DriveImage XML is now faster than ever, offering two different compression levels.

DriveImage XML runs under Windows XP, Windows Server 2003, Vista and Windows 7 only. The program will backup, 
image and restore drives formatted with FAT 12, 16, 32 and NTFS.

Free (GPL) Software.

Clonezilla is a partition and disk imaging/cloning program similar to True Image® or Norton Ghost®. It helps you to do system deployment, bare metal backup and recovery. Two types of Clonezilla are available, Clonezilla live and Clonezilla SE (server edition). Clonezilla live is suitable for single machine backup and restore. While Clonezilla SE is for massive deployment, it can clone many (40 plus!) computers simultaneously. Clonezilla saves and restores only used blocks in the harddisk. This increases the clone efficiency. With some high-end hardware in a 42-node cluster, a multicast restoring at rate 8 GB/min was reported.
